WIRE-WORKING IMPLEMENT,

SPECIFICATION forming part of Letters Patent No. 777,412, dated December13, 1904:.

Application filed April 18. 1902- To all whom it many concern:

Be it known that we, Josnr'n HIAMEL and ALPHoNsE HARDY, subjects of theKing of Great Britain, residing at Quebec city, in the Province ofQuebec, Dominion of Canada, have invented new and useful Improvements inVVire-VVorking Implements, of which the following is a specification.

This invention relates to wire-working implements in the form of pliersadapted for use by indoor wire workers,electricians in general, andlinemen especially; and the primary ob ject of the same is to provide inone implement a number of structural features which will adapt it foruse in performingdiffercnt kinds of work, and particularly in treatinginsulated wire without requiring a change of tools and a consequentdelay, as usually pursued in the old methods.

A further object of the invention is to avoid the use of knives inremoving the insulation from an electrical conductor in forminga jointand also to provide means for scraping a wire terminal to produce apractical contact by removing adhering particles of the insulation, aswell as to embody in the implement various forms of cutters and shearsand a pipe-gripping structure to assist in wiring generally.

With these and other objects and advantages in view the inventionconsists in the construction and arrangement of the several parts, whichwill beinore fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of an implement orpliers embodying the features of the invention. Fig. 2 is a partiallongitudinal vertical section of the same. Fig. 3 is a side elevation ofthe improved implement shown open.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numerals 1 and 2 respectively designate jaws similar in generalcontour to those usually found in pliers and reduced toward their freeends for obvious reasons. The inner opposing straight faces 3 of thejaws are serrated or roughened for gripping purposes, as in the ordinarystructure of pliers, and each Serial No. 103,607. (No model.)

are handles 7 and 8, suitably curved or bowed for convenience ingripping the same and operating the jaws.

Both handles? and 8 adjacent the members 4 have concave recesses 9formed therein and longitudinally corrugated or closely grooved toproduce oppositely-disposed biting-surfaces, whereby a means forgripping pipe will result similar to the ordinary pipe-tongs. The rearfree end 10 of the handle 7 is bent or arranged at an angle and reducedto form a screw-driver, and the similar end 11 of the handle 8 is bentat an angle and reduced to form a rean'ier. Projecting inwardly from thehandle 7, near the rear terminal of the same, is a scraping blade orprojection 12, which is used for scraping the exposed portions ofinsulated wire to remove particles of the insulation which may adherethereto for the purpose of effecting a practical contact either toengage a binding-post or similar device or in making joints between theterminals of two wires.

The jaws 1 and 2 also have side cutters 13 'and 1 1 for variouspurposes, and immediately behind or inward from the said side cuttersthe jaws are constructed with longitudinal slots 15 .to form an openspace through which wire may extend and be severed by the said cutters13 and 14, and thereby avoid obstruction to the closing movement of thejaws 1 and 2. In advance of the slot in the jaw 1 an inverted-V-shapedseat 16 is formed, and

adapted to depend thereinto is a cutter 17, which has clearance slots orrecesses 18 19 in front and rear of the same. The seat16, cutter 17, andslot 18 extend the full width of the jaws 1 and 2, and the use of thecutter is to separate or sever the insulation from electrical wires orconductors. In the operation of cutting or severing the insulation fromwire the latter is disposed in the seat 16 and the jaws l and 2 areclosed, thereby bringing the cutter downwardly against and forcing itthrough the adjacent portion of the insulation. During this operationthe wire and the remaining insulating material thereon at the pointwhere a portion of the latter is severed by the blade 17 moves upwardlyinto the slot 18, and the severed insulation passes into the recess 19.By this arrangement of recesses the blade will be permitted to passthrough the insulation a sufficient distance to practically separate thesame from the wire without obstruction from the remaining portion of thecovered wire because of its becoming clamped between the jaws andpreventing free movement thereof toward each other.-

From the foregoing it will be seen that a convenient implement isproduced embodying in one structure elements usually carried by severaldiiferent implements or tools, and a Workman or lineman will always havein hand and readly for operation in the one implement, as set forth, anumber of structural devices for performing different operationsnecessary in mounting or putting up electrical wires or conductors andavoid delays incident to a workman being required to put down oneimplement and take up another. The improved implement also overcomes thenecessity for the use of a penknife or other separate cutting-bladeusually employed in removing the insulation or insulating material froma wire to make a joint or contact, and painful injuries due the use ofsuch cutting operations as now commonly pursued will be prevented. It isalso understood that in certain wiring operations it is necessary todisjoint a gas-pipe, and the present implement will have means embodiedtherein for carrying on this particular work, as heretofore explained,and a great advantage in the present improved device is the economy inthe expense to workmen in procuring the same in view of the materiallygreater expense necessary to obtain separate implements or tools havingthe same features.

Although the preferred form of the improved device has been shown anddescribed, it is obvious that changes in the shape, proportions,dimensions, and minor details may be resorted to without departing fromthe spirit of the invention.

it will be observed that the forward end of the cutter 13 of jaw 1practically constitutes the inner or rearward wall of seat 16 and thatthe corresponding end of cutter 14 of jaw 2 constitutes the inner orrearward end of the slot or recess 19.

Having thus fully described the invention, what is claimed as new is- Animplement of the class set forth comprising pivotally-united jaws havinghandles for operating the same and each having a side cutter adjacent tolongitudinal slots formed in the opposing sides of the jaws to providean open space disposed centrally of the implement and having upper andlower walls which are parallel when the jaws are closed, one of saidjaws also having a V-shaped seat in advance of its cutter and the otherjaw having a V-shaped additional cutter to enter said seat, thelongitudinal slot of the jaw carrying the V-shaped additional cutterterminating at the rear side of the latter and forming a rearclearance-opening in advance of its side cutter with relation to saidadditional cutter, the front wall of the additional cutter beingvertically straight and forming the rear terminal of a rectangularclearance-recess 18 in advance thereof, the clearance recess and openingpreventing the additional V-shaped cutter from becoming jammed and thespace provided by the slots permitting the longitudinal insertion ofmaterial between the jaws for engagement by the said additional cutter.

In testimony whereof we afliX our signatures in presence of twowitnesses.
